Windows 7: GPU maddness

GPU maddness


Couple a days ago i noticed my gpu clocks are jumping all over while i am browsing the net, or using anything really, from total commander to explorer. Since i have dual monitor setup, i keep a few monitoring software's on secondary screen.
In idle the core clock is 250mhz, as soon as i move the mouse it jumps to 775mhz. Its strange since i didnt have that issue a few days ago.

On a, related issue, my card has gone nuts on YT/Twitch. While watching YT it jumps to 80% gpu usage. I checked if the hardware acc was turned on, it WASNT. I turned it on and gpu usage on YT is 10-20%, while disabled its 80%.
Same on Twitch and YT, same on Firefox and Chrome. This started a few days ago and its driving me nuts, i have less gpu usage playing games than watching YT videos in 720p.

Checked if i had any malware or such, all turned up clean. I restored a partition image 4 months old, when it all worked fine with older drivers. Same problem. Cleaned current windows with DDU and reinstalled new drivers, same problem. Both with gpu clocks and YT/Twitch gpu usage.

Mobo - Gigabyte GA-EP45C-DS3R
CPU - QuadCore Intel Xeon E5450
Ram - 2x4gb DDR2
VGA - Ati Radeon 6850 1g ram
PSU - Corsair Tx 650w

Strange thing is, that GPU clock rises, but GPU load stays low. As picture shows the clock jumping, this was browsing only, not youtube or any "heavy" content sites.

Any ideas?

To be honest, I don't see what the problem is. My Radeon card's clocks go up and down with graphics demand as well, and it's never been a performance issue with it. My card's clock doesn't jump to the extent yours does, but it's a newer generation card. That may be the reason. I tried a couple of YouTube videos and got the same results that you are getting.

As far as my card goes, it's perfectly normal behavior.

I'd have to agree with Mellon. It seems perfectly normal for a GPU to do this. Even CPUs clocks jump up and down depending on the load. Modern CPUs and GPUs are designed to be as energy efficient as they can when not on high load.

Tnx for the reply guys. I can live with clocks all over the place, it wasnt like that a few days ago, it just started by itself but it is what it is.

On YT/Twitch issue, i was playing youtube on second monitor while I worked/played, and i did it just cause the playback didn't take any resources, i mean, 5-10% is negligible. But all of a sudden it starts with 80% gpu usage, and card temperature goes up by 5-8 degrees Celsius.
Maybe they changed something on their end, i dont know.
All i know is that it wasn't like this before. I played with flash hardware acc. before, and i turned it off since it used more GPU then in software mode, now software mode uses more then hardware mode. Go figure.

Hardware acceleration in most cases is best left enabled. Hardware acceleration generally produces more fluid animation and means that means the graphical rendering is done on dedicated hardware such as your GPU instead of putting more stress on your CPU.

Yep just switch to a high performance power plan and boogie on :)

It was bad in XP, but seems worse in Win7. Clipboard doesnt seem to hold onto last Copied item long at all. I will copy a string of text and if I I dont paste it very soon after it wont paste. Usually I hcopy a piece of text, and if I have to minimize a few windows or do too many keystroke...
